Cov txheej txheem proportions thiab ntau lawm txheej txheem ntawm steel fiber hnav-resistant castables thiabsteel fiber ntau castablesyeej yog tib yam. Qhov txawv yog tias silicon carbide ntxiv rau cov hlau fiber ntau hnav-resistant castables. Silicon carbide yog hnav-tiv taus thiab plays lub cev pob txha hauv kev siv.
1. Qhov txawv ntawm ob
Ob lub castables yog tsim nrog tus nqi tsim nyog ntawm stainless hlau tshav kub-resistant fiber. Nws kuj muaj qhov ua tau zoo heev rau kev ua kom txias sai, cua sov sai, thiab tensile tsis kam. Qhov txawv yog qhov cuam tshuam tsis kam thiab hnav tsis kam yog qhov sib txawv. Hlau fiber ntau hnav-tiv taus castables yog hnav-tiv taus ntau dua li cov hlau fiber ntau castables. Qhov sib ntxiv ntawm steel fibers, los tiv thaiv cov castable los ntawm resisting invasion ntawm kub gradient hloov thaum pib thiab nres lub cub tawg, tiv thaiv kev nyuaj siab puas tsuaj, thiab txhim kho lub zog ntawm castable.
2. Kev ua haujlwm ntawm steel-fiber castable yog ruaj khov dua
Cov hlau-fiber castables feem ntau yog siv rau hauv cov kab hluav taws xob hauv qab 1350 degree, thaum cov castables ntxiv nrog silicon carbide feem ntau yog siv hauv boiler rauv tawm thiab boiler sab phab ntsa. Thaum ntxiv cov hlau fiber ntau thiab silicon carbide, kev ua haujlwm ntawm cov castable yuav ruaj khov thiab hnav-resistant thaum siv.
3. Kev piav qhia ntawm cov haujlwm sib txawv ntawm ob
Ob lub castables no muaj nyob rau tib lub koob, tab sis lawv cov dej num sib txawv, feem ntau cuam tshuam txog qhov sib txawv ntawm kev hnav tsis kam. Txawm li cas los xij, thaum lub sij hawm tsim kho, cov txheej txheem nchuav yog tib yam, tab sis nyob rau hauv cov txheej txheem ntawm kev tsim khoom, muaj qhov sib txawv ntawm kev ntxiv thiab tsis ntxiv silicon carbide. Tsuas yog cov khoom xyaw, tus nqi ntawm cov hlau fiber ntau thiab silicon carbide ntxiv thiab kev tsim kho yog tag nrho cov kauj ruam tseem ceeb thiab kev sib txuas los txhim kho lub neej kev pab cuam ntawm steel fiber castables. Thaum ntxiv silicon carbide castables, xyuam xim rau cov ntsiab lus oxidation. Castables ntxiv nrog silicon carbide tsis tuaj yeem siv rau hauv qhov chaw uas muaj cua txias, vim tias lawv yuav raug oxidized los ntawm cua txias. Tsis tas li ntawd, qhov cub hauv ob sab phlu hauv qhov chaw oxidizing tsis haum rau xaiv, thiab cov hlau fiber ntau hnav-resistant castable nrog silicon carbide ntxiv yog tsis haum.
Muaj qhov zoo sib xws thiab qhov sib txawv ntawm cov hlau fiber ntau castables thiab steel fiber ntau hnav-resistant castables, thiab qhov zoo ntawm cov ntaub ntawv siv nyob ntawm seb cov xwm txheej ntawm cov kab sib txawv ntawm lub qhov cub.
